After review the 2D Yang-Mills theories (YM2) and its
large-N behaviour, the Generalized 2D Yang-Mills theories
(gYM2) and their partition functions on a general
two-dimensional Riemann surface are discussed. The large-N
behaviour of these models is studied in weak regime, and in strong
regime, we restrict ourselves to ϕ4 gYM2. We show
that this model has a third order phase transition, similar to
ordinary YM2 theory.
